To (LZZ whmn. it may concern:

Be 1t-k nownthat I, ROBERT ANDERSON, a

citizen of the United States of America, and i a resident of Cincinnati, county of Hamilton,

State of Ohio, have invented certain new and In the accompanying drawings, Figure 1 is a cross-sectional View of a column and a beam covered with a reinforced concrete embodying my invention.- Fig. 2 is a crosssection of the same. Fig. 3 is an elevation of the wire bent into return-bends in the form in which itis supplied to the workmen before it has been extended for engaging the beams.'

Fig. 4 is a detail view, upon an enlarged scale, showing the flange of the beam in cross-section and a section of wire applied thereto. Fig. 5 is an inverted plan view of an I-beam with the wire return-bends engaging the same.

Referring to the parts, the wire A is bent into, a series of return-bends a, wherein the successive members stand substantially parallel to each other. The-ends of the bends are bent into hooks a, as shown in Fig. 3. The wire in this form is supplied to the workman, who engages it with the flange 6 of a l beam B by engaging one of the hooks a with the flange, then the successive hooks a, spreading the parallel members apart at angles such that the hooks are made to grasp the flange firmly. After the hooks have been thus engaged with-the flange of the beam the wire stands at a short distance from the surface of the flange. When the concrete C is placed about the beam, it fills in the spaces between the wire and the beam and takes a iirm grip upon the wire, so that it prevents the concrete being separated from the beam.

The process of applying the wire to a beam is a simple and rapid one, and the wire may be bent into the economioall l/Vhat I c aim is her, a continuous Wire bent into return-bends, means at theends' of the bends engaging the structural member and concrete'eovering the wire and the member.

2. The combination of a structural member, a wire bent into return-bends, the returnbends bent at. the ends into hooks, the hooks engaging the edges of the member, and concrete covering the wire and the member.
